Description

Technical Field

[0001] This utility model relates to the field of double-sided adhesive technology, specifically a double-sided adhesive with an anti-slip release film structure. Background Technology

[0002] Double-sided tape is a common adhesive material. Both sides are coated with an adhesive substance, allowing it to bond two surfaces simultaneously without the need for additional glue or other adhesives. It is convenient to use, provides a strong bond, and has a wide range of applications, making it widely used in daily life, industrial production, office settings, and many other fields.

[0003] For example, the utility model patent disclosed in publication number CN204625543U discloses a novel double-sided adhesive tape, comprising a base layer, an upper surface of which is covered with a polymer layer, a movable pressure-sensitive adhesive layer is disposed on the upper surface of the polymer layer, and an isolation layer is disposed on the upper surface of the movable pressure-sensitive adhesive layer; the lower surface of the base layer is covered with a polymer layer, a fixed pressure-sensitive adhesive layer is disposed on the lower surface of the polymer layer, and an isolation layer is disposed on the lower surface of the fixed pressure-sensitive adhesive layer; L-shaped positioning slots with opposite directions are respectively provided on both sides of the polymer layer. This utility model has a reasonable design and is easy to position. It uses L-shaped positioning slots to achieve accurate and rapid positioning of the double-sided adhesive tape. At the same time, this utility model has good performance, improving the overall anti-slip properties, barrier properties, heat resistance, and light-blocking properties. By designing pressure-sensitive adhesive layers with different adhesive strengths, it can save materials while meeting different adhesive bonding needs, and has good application prospects.

[0004] Although the aforementioned double-sided tapes have certain material-saving functions, the anti-slip performance of the release film of these double-sided tapes is insufficient, making it difficult to quickly separate the release film from the tape body, thus reducing the practical performance of the double-sided tapes. Therefore, there is an urgent need for a double-sided tape with an anti-slip release film structure to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a double-sided adhesive with an anti-slip release film structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-sided adhesive with an anti-slip release film structure, comprising a double-sided adhesive layer, wherein a release film layer is provided at both the upper and lower parts of the double-sided adhesive layer, and a support layer is fixedly provided at the outer end face of the two sets of release film layers.

[0007] A waterproof layer is fixedly disposed on the outer end face of the support layer;

[0008] The outer protective layer is fixedly disposed on the outer end face of the waterproof layer. The upper end face of the outer protective layer is provided with an anti-slip mesh, and protective protrusions are provided at equal intervals on the upper end face of the outer protective layer. The outer protective layer is used for protection and anti-slip.

[0009] Preferably, the release film layer is made of PET, which has strong corrosion resistance and stable and adjustable peel force as a release film, thus improving the adaptability of the double-sided tape.

[0010] Preferably, the support layer is made of OPP and serves as a support structure in the middle layer of the release film, which can prevent breakage when the outer protective layer and the release film are subsequently torn.

[0011] Preferably, the waterproof layer is made of PVC, which can effectively improve the waterproof performance of the double-sided adhesive layer and thus improve the protection of the double-sided adhesive layer when it is not in use.

[0012] Preferably, the protective outer layer is made of PE, which can effectively improve the protective performance of the release film layer.

[0013] Preferably, the protective protrusion has a tapered cross-section, which can effectively improve the anti-slip performance between the protective outer layer and the user's hand, thereby improving the efficiency of subsequent removal of the protective outer layer and release film.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting protective protrusions, anti-slip mesh, and a protective outer layer, provides sufficient friction for the outer layer when separating it from the double-sided adhesive layer. This improves the ease with which the user can remove the outer layer and release film. Simultaneously, the multiple sets of anti-slip mesh on the outer layer enhance the lateral and longitudinal stability of the outer layer and release film, further improving the anti-slip performance. This, in turn, increases the ease of separating the outer layer, release film, and double-sided adhesive layer, thereby enhancing the practicality of the double-sided tape.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2 One embodiment of this utility model provides: a double-sided adhesive with an anti-slip release film structure, comprising a double-sided adhesive layer 7, with release film layers 6 disposed on both the upper and lower parts of the double-sided adhesive layer 7, and a support layer 5 fixedly disposed on the outer end face of the two sets of release film layers 6.

[0021] Waterproof layer 4 is fixedly installed on the outer end face of support layer 5;

[0022] The outer protective layer 3 is fixedly installed on the outer end face of the waterproof layer 4. The upper end face of the outer protective layer 3 is provided with an anti-slip mesh 2, and protective protrusions 1 are provided at equal intervals on the upper end face of the outer protective layer 3. The outer protective layer 3 is used for protection and anti-slip.

[0023] The release film layer 6 is made of PET. PET has strong corrosion resistance, and as a release film, its peel force is stable and adjustable, which improves the adaptability of double-sided tape.

[0024] The support layer 5 is made of OPP and serves as the support structure in the middle layer of the release film layer 6. It can prevent breakage when the outer protective layer 3 and the release film layer 6 are subsequently torn.

[0025] The waterproof layer 4 is made of PVC, which can effectively improve the waterproof performance of the double-sided adhesive layer 7, thereby improving the protection of the double-sided adhesive layer 7 when it is not in use.

[0026] The outer protective layer 3 is made of PE, which can effectively improve the protective performance of the release film layer 6.

[0027] The protective protrusion 1 has a tapered cross-section, which can effectively improve the anti-slip performance between the protective outer layer 3 and the user's hand, thereby improving the efficiency of subsequent removal of the protective outer layer 3 and the release film layer 6.

[0028] Working principle: When separating the protective outer layer 3 from the double-sided adhesive layer 7, the protective protrusion 1 is cone-shaped, which provides sufficient friction to the outside of the protective outer layer 3, improving the ease with which the user can remove the protective outer layer 3 and the release film layer 6. At the same time, the multiple anti-slip meshes 2 on the outside of the protective outer layer 3 can improve the lateral and longitudinal stability of the protective outer layer 3 and the release film layer 6, and further improve the anti-slip performance of the outer layer 3, thereby improving the ease with which the protective outer layer 3 and the release film layer 6 are separated from the double-sided adhesive layer 7, thus improving the practicality of the double-sided tape. Meanwhile, the waterproof layer 4 is made of waterproof material, which can prevent external moisture from affecting the adhesion of the double-sided adhesive layer 7, and the support layer 5 can further improve the overall stability of the protective outer layer 3, preventing breakage when the protective outer layer 3 and the release film layer 6 are subsequently removed.
